Who advocated that art must remain free from the concerns of its time?

The idea that art should remain free from the concerns of its time is often associated with the Russian formalist critic Viktor Shklovsky. He argued that art should prioritize its own aesthetic qualities and techniques rather than being influenced by social or political issues. This perspective emphasizes the autonomy of art and its ability to transcend contemporary realities. Shklovsky's views contributed to a broader discourse on the relationship between art and society.
